JAMES W. AMES, 0}? MONTGLAIR, AND LOUIS J. BATZLE, OF BAYONNE, NEW JERSEY, ASSIGNORS T0 W. AMES & 00., OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY.

Application filed March 7, 1910, Serial No. 547,721.

To all whom it may concern:

Be it known that we, JAMES V. AMEs, a citizen of the United States, residing at lvlontclair, in the county of Essex and State of New Jersey, and LOUIS J. BATZLE, ac1t1- zen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Spike-Machines, of which the following is a full, clear, and exact specification.

Our invention relates to machines for forming spikes, such as railroad spikes, and to the method whereby such spikes are formed.

The invention is illustrated in connection with a type of machine known as the Cary machine, to which it is particularly applicable, and by means of which said machine is rendered capable of automatic action, whereby its capacity is greatly increased. Our invention, however, is not limited in its application to such particular type of machine, but is applicable, also. to other types of machines for forming spikes and analogous articles.

In the use of the ordinary type of such Cary machine, the stock is fed in by hand and a cutter moves horizontally across the line of feed and cuts the blank off, leaving a vertical fin on that part of the stock which is to form the head of the next spike. To insure uniformity in the two sides of the spike, it is essential that the stock should be given a quarter turn before the next blank is cut oil,-and this operation, which is performed by hand, is an obstacle to the automatic operation of the machine. The application of our invention to such machine obviates the necessity for turning the stock in the machine and also finishes the entire spike, including the point, in one operation.

These objects we attain by imparting a new function to the movable point-forming die; to wit, that of serving the newlyformed spike from the stock, which function is accomplished by giving the said die a capacity for lateral movement substantially in the direction of the feed and by providing means whereby said die is given a movement which severs the stock from the spike and finishes the point of the spike, and by providing a stationa y bottom-pointing die to Specification of Letters Patent.

SPIKE-MACHINE.

Patented May 4, 1915. Renewed September as, 1914. Serial No. 863,221.

cooperate therewith. method whereby this result is accomplished are as follows: (1) The stock from which the spike is to be formed is suitably clamped against the bottom dies and chills; (2) The body-pressing and point-forming dies are then brought forcibly down into contact with said stock, to shape the same and press a point thereon; (3) The head-forming die is forced against the blank, which movement may begin before the point-forming die has ceased its first movement; (4:) The pointforming die as it completes its pressing movement is moved against the stock, severing it from the newly-made spike; and (5) The finished spike is then ejected.

The material used for forming the spikes is usually heated to obtain the best results and the parts of the dies that come in contact therewith, as well as those parts that receive excessive wear, are usually hardened.

One embodiment of our invention is shown in the accompanying drawings which illustrate the same applied to a spike ma chine of the Cary type, and in connection therewith our new method may be easily understood.

In the said drawings Figure 1 is a front elevation of the said machine. Fig. 2 is a rear elevation thereof. Fig. 3 is a side elevation, looking at the machine from the right of Fig. 1. Fig. 4 is a plan view of the machine, parts being omitted for clearness. Fig. is a detail of the dies and chills; and Fig. 6 is a sectional detail of the same parts on the line 05-4; of Fig. 1, looking toward the left.

The machine has a base 1, upon which, at the rear of the machine, are standards 2, 3, in which the driving shaft 4 is borne. This shaft has fixed thereon a driving-pulley 5, and a balance-wheel 6. l

A frame 7 is secured to the base 1, in this instance being cast integral. therewith, and within said frame are secured the stationary bottom dies and chills, by means of threaded bolts 8, which are passed through threaded openings in the side of said frame. The said dies and chills comprise the gripping and head-forming lipped die 9, the lippedchill 10, and the pointing chill 11. These are secured laterally on one side by the frame 7., and on the other by a block 12,

The steps of the against which the bolts 8 bear. A plate 13 is bolted to the top of the pointing-chill 11, and at the other end receives a bolt which passes'through a slot 14 in the block 12.

, This plate 13 is to prevent rising of the dies I chill 10 and is beveled to form the lower holes on said frame and bear against a gripping-chill 23, which lies at one side of said gripping-die, and keeps the stock from spreading and warping while being pointed and headed. On the other side is a block 24, bolted to which is a plate 71, which passes over the top of the die and prevents its rising.

The frame 21 is mounted on the end of a bifurcatedrockingarm 25, which is journaled on a shaft 40, having bearings in brackets 26, 27 depending from cross-bars forming part of the base of the machine. An operating-arm 28 is attached to said movable frame 21 and projects toward the rear of the machine therefrom, rising so that its rear 'end is above the driving shaft and'within the path of a cam-wheel 29 on the driving-shaft. This cam-wheel is ofiset axially on one side, whereby, as it revolves, it imparts a sidewise motion to the operating-arm 28 and causes the moving gripping-die 20 to move in the arc of a'circle around the shaft 40 of the rocking-arm 25, and the lip on die 20 then passes over the stock, gripping the stock 7 0 between dies 20 and 9, and between chills 24 and 10 and 11. The completion ofthe revolution of the camwheel 29'releases the operating-arm 28, and the frame 21 returns by gavity to its initial position. The said gripping-die 20 and chill 24 press the stock firmly against grippingchill and dies 9, 10, and 11, and serve to hold the stock while the head and point are being 72 passing through the frame. The frame 32 is supported in a rocking cross-head 33, and enters a recess 34 formed in the under side thereof. Flanges 35 project laterally from both sides of said frame and rest on plates 36, bolted to the underside of said cross-head and permitting the frame to slide crosswise relative to the head. A fiatspring' 37 is bolted to the crosshead and returns the frame to its place when it is moved forward. The rearward movement of the frame may be stopped by any suitable stop, as by a plate 38 ontherear wall of thecross-head (Fig. 6).

The cross-head 33 has rocking-arms 39, 39 which have bearings on short shafts journaled-in posts 41, 42, at the front of the machine, and the cross-head likewise has an operatmgarm 43, which pro ects rearwardly of the machine and over the driving shaft, where it'is connected by pitman 44, to

a crank-pin on crank-wheel 45, which is fixed to the driving-shaft 4. Bolts 46, 47, are provided, which pass through threaded holes in frame 34 and engage the rear of dies 30, 31, to support and adjust same,and these bolts slide in a slot 48 in the crosshead 33. The said parts are omitted from the plan view of the machine (Fig. 4) for clearness in illustrating the parts that lie beneath them, but are clearly illustrated in the remaining figures.

In the particular embodiment illustrated the pointing-die moves in a direction transverse of the body of the spike to be formed around the pivots of the cross-head 33, and said die likewise has a movement lengthwise of said spike caused by'the sliding of -the frame forward in the cross-head. By means of such movements, as the pointing-die is brought down upon the stock by the rocking of the operating arm, it cuts a point upon the stock by the cooperation of the bottompointing die 15, and as a lengthwise movement is imparted thereto just prior to the completion of its transverse movement, it

will sever the newly-pointed spike from the j stock at the same time die 31 presses and straightens the body of the spike.

The movable gripping-die has its side its face to form the head of the spike and is heldrin a recess 51, in a rocking-arm 52 (seen in dotted lines in Fig. 3), which is actuated by an operating-arm 54 which passes rear- .wardly and over eccentric lug 55, which is fixed to the driving-shaft and revolves there- -with. Rocking-arm 52 turns on a shaft 56 (seen in dotted lines in Fig. 2), supported in brackets57, 58, depending from the side bars in the base.

Arrows in the different views show the direction of revolution of the driving-shaft,

from which it will be seen that as'the lug 55 is turned and engages operating arm 54,

the heading-die is driven forward upon the stock and presses same toward the front of the machine and into the recesses on the stationary and movable heading dies.

An important feature of our invention is the supplemental or sliding movement imparted to the movable pointing-die. Such movement may be imparted in a number of ways and one desirable manner of so imparting it is shown in the drawings, where such movement is given by the movable headingdie. A block 59 is suitably secured to the heading-die, as by being bolted thereto, and a strap 60 is then passed over the said block and is bolted to side-posts 73, projecting upwardly from rocking-arm 52, whereby the said parts are securely assembled. The rear H and side walls of recess 51 and the strap 60 hold the heading die and block and enable them to exert the proper pressure.

The block 59 is so adjusted that preferably it will engage the sliding-frame 32 before the pointing-die has completed its circular movement and, of course, before the heading-die has completed the head. A slight movement of the heading-die will then remain preferably about i to inch, which will cause the pointing-die to have an equal extent of movement transverse of the crosshead 33, which will be suflicient to complete the point and, in cooperation with bottom-die 15, to sever the newly-made spike from the stock. The best results have been obtained by having the latter part of the supplemental or sliding motion of the pointing die take place after the movement of said die in the arc of a circle has been completed, and when the said movable pointing-die is in its lowest position, where it is substantially over the bottom-pointing die. The balance of. the supplemental motion will carry the movable pointingdie slightly past the stationary or bottom-pointing die and thereby completely sever the stock.

After the heading-die has performed its work and the lug on the driving-shaft has passed its operating-arm, the rocking-frame falls back by gravity and is received on a cross-bar of the base of the machine. The finished spike is then ejected by an ejector 61, which Works crosswise of the machine and the front end of which passes through a slot 62, in a stationary chill 10, and which ejector by its forward movement discharges the finished spike from the dies. Said ejector is operated by a lever 63, turning on a pivot 6 L, fixed to the base and having an upwardly-turned end which passes within the path of cam 65, on cam-wheel 66, carried by the driving-shaft.

A retracting-spring 67 is secured at the top of post 3, at the rear of the machine, and is attached to an eye 68, on the lever 63, by hook 69, and serves to retract the ejector after the passage of cam 65 by the end of lever 63.

our present invention and such automatic,

feeds are well known.

The operation of our improved machine and our improved methodof forming spikes V are as follows: The stock is fed from the front of the machine to the bottom diesand chills, where it is clamped in position by the moving gripping-die and chill. The stock being thus firmly held between the upper and lower gripping-dies, the bodypressing and pointforming die approach the stock and press it against the bottom dies and chills, and the movable point-forming die in cooperation with the stationary point-forming die begin forming the point. This is accomplished by a cutting action whereby the metal at the point is cut. Be fore the moving pointing-die has completed its stroke, the moving header, which has in the meantime been moved forwardly in the performance of its head-forming function, has progressed so far that its block engages the frame carrying the pointing-die and gives the same a slight forward movement of 9, to inch, according to adjustment. The latter part of this movementabout one-half of ittakes place after the movable pointing-die has completed its movement in the arc of a circle, and when it is at its lower point. The said supplemental motion, therefore, has the effect of moving the pointing die when in lowest position lengthwise of the spike which will sever the stock in connection with the bottom-pointing die. By this time the head is completed and said supplemental movement of the pointingdie completes the point and severs the stock. The moving dies then withdraw and the. ejecting mechanism discharges the completed spike.
